【摘要】 研究了缺氧/好氧强化生物絮凝—生物膜工艺对生活污水COD_Cr、NH₃—N、TN、TP、浊度的去除效能和机理。试验结果表明:缺氧池、絮凝池的最佳HRT之比为3.6/2.4;絮凝池最佳DO为0.5mg/L;最佳流量为4m³/d。在最佳工艺运行参数条件下,COD_Cr、NH₃—N、TN、TP、浊度的平均去除率分别为95.05%、44.91%、39.43%、63.46%、71.03%,出水COD_Cr、SS达到《城镇污水处理厂污染物排放标准》（GB 18918—2002）一级B标准,TP接近达标。更多还原

【Abstract】 A full-scale experiment was conducted on treatment of swage by anoxic/oxic en- hanced bio-flocculation plus velocity-changed bio-filter process.The experimental results showed that the optimal working conditions were anoxic tank HRT of 3.6h,oxic tank HRT of 2.4h and DO of 0.5mg/ L,flow quantity of 4m³/d.The removal of COD_Cr was 95.05%,those of NH₃-N,TN,TP and turbid de- gree were 44.91%,39.43%,63.46%,and 71.03% respectively.The quality of the effluent can partially meet the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918-2002）.更多还原
